Synth Coins (SC) are the Synthonia currency: they are required to be able to download our contents and purchase Gadgets and Musical Instruments. You can earn the exact number of SC you need, or you may buy one of the available SC packs. Our offers include savings proportional to the amount of the chosen pack. The bigger the pack, the lower the price of the single SC.
